Which NSX-T feature allows for automation of network and security policies?

The feature that allows for automation of network and security policies in NSX-T is policy-driven automation. This approach enables organizations to define specific network and security policies that can be automatically enforced throughout the environment. It ensures that any changes or updates to policies are efficiently propagated across the virtual networking infrastructure without manual intervention.

By employing policy-driven automation, administrators can define rules based on various parameters like application requirements, compliance needs, and organizational best practices. This results in greater agility, consistent policy application, and reduced chances of human error.

Service chaining, while useful in configuring how traffic flows through services, does not inherently automate the creation or management of network and security policies. API integration facilitates automation through programmatic interactions, but it does not specifically pertain to the conceptual framework of automating policies. Federation allows for the stretching of NSX-T services across different data centers but is not about the automation of network and security policies themselves.
